The following consists of a set of daily maps of sea level pressure
(hPa), 500-hPa geopotential height (m), lifted indices (LI; °C),
and surface to 500-hPa wind shear (m s-1). The top panels
are the analyzed data, determined from the National Centers for
Environmental Prediction (NCEP)-National Center for Atmospheric
Research (NCAR) reanalyses. The middle panels are 2-day forecasts
that are valid at the same time as the analysis data. The bottom
panels are 5-day forecasts valid at the same time.
